Specification of Letters Patent.

Serial No. 400,586.

To all whom it may concern:

Be it known that I, ARTHUR GREEN, sub ject of England, residing at Whittington Moor, near the town of Chesterfield, in the county of Derby, England, have invented new and useful Improvements in Moldin Machines, of which the following is a speci 1- cation.

Molding machines as ordinarily made besides being restricted as to the size of box with which they can be used, are complicated in their mechanism and consequently are an expensive commodity, especially when additional machines have to be employed for every varying size of box.

The object of my invention is to construct a molding machine that shall be much simpler in its action, lighter in its construction, and adapted for use with several sizes of boxes.

I carry out my invention in the following manner.

The nature of my invention will be better understood on reference to the accompanying sheet of drawings in which,

Figure 1. is a side elevation, part in section, of one of my improved machines. Fig. 2 is a plan, also part in section, the stripping plate being removed. Fig. 3 is a side elevation of the duplex arrangement, and Fig. 4 is a plan, part of the stripping plate being shown broken away.

The same letters refer to similar parts throughout the several views.

The body or standard, a, I make of either wrought or cast metal, in the form of a double ended cone, through the smallest diameter or waist of which I form a longitudinal slot, Z), through which I pass a lever, 0, one

end of which is carried on a suitable bracket,

d, outside the cone and the other end of which works in a vertical or radial slide, 0, provided with notches by which the lever, 0, may be held in any desired position, and in some cases I provide a weight, 0 at the short end of the lever to balance the weight of .the ram, f, and its head and the long end of the lever.

Down the center of the cone I provide a ram, f, which works in sockets or guides, g, 9 both at the top and bottom of the stand, to keep it in line vertically and I also provide additional guides on either or on both sides the ram or I make the ram and the guidessquare to prevent the pattern plate from turning sidewise. I form an elongated slot, 0 in this ram through which the hand lever, a, previously described is free to work, so that the ram may be worked upwards or downwards by the said lever as may be required. On the top of this ram I provide a head, y', to which I affix the various sizes of pattern plates employed with the machine.

On the top of the machine I provide lugs or brackets, is, for carrying four or more radial slotted arms, Z, which can be drawn out from or pushed in towards the center of the machine to any required position, and then secured by bolts or studs to the previously named lugs or brackets; The outer ends of these sliding arms, I provide with holes to receive the ends of screwed bolts or studs, m, by which the stripping plate, n, is carried. The stripping plate being provided with corresponding holes to recelve the countersunk ends of the said bolts and by employing nuts under the said stripping plate and also above and under the sliding arms, the whole may be secured and leveled in any desired position; to obviate the necessity of removing the nuts ofl' the bolts every time the stripping plate is changed, I form the holes in the sliding brackets or arms, Z, and in the stripping plate, n, with end slots, so that when .the nuts are slackened the bolts, m, can be drawn out sidewise instead of vertically. To'do this it would only be necessary to slack the nuts on the underside of the stripping plate and on the underside of the sliding brackets or arms, Z, a sufficient distance, to allow of the heads being raised clear of the countersunks. The top of my improved machine, I form so as to give support to the sliding brackets or arms, Z, at their inner V ends as Well as at their outer ends, so that when they are drawn out to their maximum length to accommodate the largest size stripping plate, the inner ends'will still have a bearing some distance inwards.

From the foregoing description it will be seen that by changing the pattern and stripping plates, n, my improved molding machine can be adapted for use with several sizes of boxes.

From the foregoing it will also be seen that two machines as herein described, can be placed to work together side by side a sufficient distance apart, to accommodate a box which would be too long to be conveniently carried on one machine. In such case the stripping and pattern plates, 9', I make long enough to be secured and Worked With both machines.

For certain classes of Work I construct a duplex or twin machine as shown in Figs. 3 and 4 so that the standards'a can be fitted to one bedplate 0 and made to slide nearer together or further apart according to the class of Work on Which they are to be employed. Such duplex machines however, Would in their individual parts be unaltered and Would be adapted to Work separately and independently of each other.

What I do claim and desire to secure by Letters Patent is 1. A molding machine comprising a standard, a ram movable vertically therein, a head on said ram, radially movable arms on the top of said standard, and a stripperplate removably carried by said arms.

2. A molding machine comprising two standards, a ram in each standard, a head on each ram, means for moving the rams vertically, radially movable lugs on the top of the standards, and a single stripper plate carried by said lugs.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

ARTHUR GREEN.
